Now, you may want to try to debug this problem using standard tools, like perhaps strace, ltrace, maybe lsof, and a few others. We have seen this before, in the Linux Kernel Crash Book examples.Īnd then, we run it and get a nasty segmentation fault: This is done by using the -g flag when running gcc. This will normally lead to an unhandled error, resulting in a segmentation fault. In layman’s terms, null pointer is a pointer to an address in the memory space that does not have a meaningful value and cannot be referenced by the calling program, for whatever reason. We will begin with a simple example – a null pointer. You should also be familiar with the AT&T Assembly syntax, which is the syntax used in Linux, as opposed to Intel syntax, for example.Īll right, if you meet all of the above – or wish to – then you can proceed.

You should also be able to navigate /proc with some degree of comfort. Then, the fundamental concepts like code, data, heap, stack and whatnot. First, you will need some core knowledge of the memory management in Linux. This is probably the most important element. However, if you really find the concepts alien and you struggle with compilations and working on the command line in general, perhaps this topic is a little advanced for you at the moment. This tutorial will teach you a handful of basic and intermediate commands, so you need not worry too much about that. Otherwise, you will be sort of groping in the dark. On top of that, you will want sources with symbols, so you can map instructions in the binary program to their corresponding functions and lines in the source code. You will only be able to follow symptoms and try to figure out where things might be wrong, but not why.

However, your task will be more difficult, because you will not be able to refer to the actual code and try to understand if there’s any kind of logical fallacy in the execution. You can debug code without having access to source files. There are many requirements you must meet before you can have a successful session. Working with gdb is not something anyone can do at their leisure. This won’t be easy, but it sure will be one of the best super-duper admin guides you have read so far.

Today, we will learn how to handle misbehaving binary code, how to examine its execution step by step, how to interpret errors and problems, and we will even step into the assembly code and hunt for problems there.

Luckily for you, the ultimate combination of the GNU Debugger (gdb) and Dedoimedo tutorials will help you overcome the problem. For all practical purposes, you call it a day. The only problem is, the execution fails with a segmentation fault. Or you have a binary and you just run it. So you wrote a piece of code and you want to compile it and run it.
